Search seems slow with apache solr
by Steve Dondley 05 Apr '21

05 Apr '21

I'm experimenting with Apache Solr and Dovecot. As far as I can tell, I have dovecot working with Apache Solr as demonstrated by this output: a search text "cash" * SEARCH 4 8 26 35 45 52 54 55 63 a OK Search completed (0.356 + 0.001 + 0.068 secs). However, when using the roundcube search bar and search all messages on a single word, it takes about 18 seconds. This seems slow as I only have about 4300 message in all my folders. But I'm not sure as I have nothing to compare it to. Is there a way I can test whether roundcube is using solr to perform searches?

Mass Stripping Attachments by Directory, Age, Size
by Plutocrat 05 Apr '21

05 Apr '21

Hi, I've been looking around for a solution to this problem. I want to prune down the attachments on a server before a migration. Some of the emails are 7 years old and have 40Mb attachments, so this seems like a good opportunity to rationalize things. So perhaps I'd like to "Remove all attachments from emails older than 2 years, in the .Sent directory", or "Attachments over 10Mb anywhere in the mail tree" I've found the strip_attachments.pl script here <https://fossies.org/linux/Mail-Box/examples/strip-attachments.pl> which works fine on mbox (as tested on my local Thunderbird mboxes), but not on maildir which is on the dovecot server. My Perl isn't strong enough to re-purpose it. I've looked at ripmime and mpack/munpack, and although they seem like useful tools to do the job of deconstructing the mail into its constituent parts, it doesn't seem to help in re-building the email. I think they could be used with a bit of study into mail MIME structure, and used with a helper script. So before I take a deep dive into scripting my own solution, I just wanted to check if anyone else on the list has been through this and has some resources or pointers they can share, or maybe even someone to tell me "Duh, you can do it with doveadm of course". P.

thunderbird copy old messages from other dirs
by Brian 04 Apr '21

04 Apr '21

Is there a known documented way to copy messages from backup folders into the cur folder and have them not make a mess of the dates. What I see is if I copy several year old messages to the cur folder on an ubuntu box the massages when viewed on an android phone appear out of order. I tried deleting the dovecot index and cache files and restarting the service, I also tried running these 2 scripts I found. I added some echoes to see what was occurring. Still, messages appear out of order and some do not appear at all on the droid. I tried copying the actual message files out of various cur dirs and still some were very out of date. The second script seemed to be adjusting the dates of the files properly, but I am not sure what android gmail actually uses to sort. #!/bin/bash for i in `ls /home/brian/Maildir/cur/` do # Find the date field and then remove up to the first space (Date: ) DATE=$(grep '^Date:' $i | head -1 | cut -d' ' -f1 --complement) # Create a timestamp from the date above STAMP=$(date --date="$DATE" +%Y%m%d%H%M) # touch the file with the correct timestamp touch -t $STAMP $i echo "$i stamped" echo "$DATE" echo "$STAMP" done ------------ #!/bin/bash # Fix emails with bad timestamps in a maildir # This script reads the date from the email header and set its UNIX timestamp and renames it with the proper date # e.g. this: # dec. 05 2017 1512499812.M908995P21566.ip-111-11-11-11,S=16331,W=16746:2,S # becomes that (the email Date header is "Date: Tue, 22 Oct 2013 10:07:21 +0100"): # oct. 22 2013 1382432841.M908995P21566.ip-111-11-11-11,S=16331,W=16746:2,S cd "/home/brian/Maildir/cur"; for i in `ls 1482809425.M277770P17438*` do echo "$i" # We extract the date from the email headers DATE=$(grep '^Date:' $i | head -1 | cut -d' ' -f1 --complement) # We compute a touch-compatible timestamp as well as the real timestamp TOUCHSTAMP=$(date --date="$DATE" +%Y%m%d%H%M) TIMESTAMP=$(date --date="$DATE" +%s) # We set the file timestamp touch -t $TOUCHSTAMP $i # We rename the file with preprending timestamp newfilename="$TIMESTAMP.${i#*.}" mv "$i" "$newfilename" echo "$newfilename" echo "******" done

.IMAP locations
by Elise 03 Apr '21

03 Apr '21

I have this account, /usr/home/me To be able to admin websites, I created a folder /usr/home/me/www , containing my siteroot /usr/home/me/www/mysite.com My dovecot.config: mail_location = mbox:/home/%u:INBOX=/var/mail/%u the actual mailfolder is /usr/home/me/mail , which I defined in my mailclient as 'mail/' The issue now is that Dovecot is indexing my whole /usr/home/me/ folder, including the www folder, in which it also idexes every folder that is in /usr/home/me/www/mysite.com . It puts in these folders an .imap folder that is containing the exact content of the folder it is put in. So my site takes double space by this Dovecot indexing. To solve this issue, I defined my mail_location line as mail_location = mbox:/home/%u/mail:INBOX=/var/mail/%u and removed the 'mail/' directive from my mail client. For some reason this does not prevent Dovecot to index the subfolders of /usr/home/me/www/ - Do I have to remove all Dovecot related indexing files by hand to solve this and restart Dovecot service afterwards? - Can you tell me how I can define the Dovecot index files location so that there will be no .imap folder created anymore in my /usr/home/me/www/ subfolder(s)? Thanks for you help! Elise #CSSis {beautiful};

Seeking Advice for data recovery
by Riccardo Bicelli 03 Apr '21

03 Apr '21

Hello, we had a drive failure and needed to restore our dovecot server to operational status in no time. So we restored an "old" snapshot backup and worked on the failed drive in order to recover the mails. Data backup didn't worked :-( Now the storage is updated with mails from beginning of time to snapshot, and from recovery day to now, and a copy of the storage of mails from beginning of time to failure. Is there a way to "inject" the mails from "snapshot to failure"? Which is the best way? We're using mdbox. Thanks, Riccardo

Emails Ending up in Junk
by Asai 03 Apr '21

03 Apr '21

Greetings, I'm trying to debug an issue with a user who is finding emails (user uses Thunderbird as client) ending up in Junk folder, and constantly marks email as Not Junk, but important email ends up in Junk folder. I have sieve set up, but am unable to determine if this is the result of a sieve problem (sieve will automatically move certain emails into Junk if certain headers are present, but these headers are not present on these emails.) I'm looking in Dovecot debug logs to try to figure this out, but all I can find is sometimes this, and I don't know if this is relevant. Can anyone point us in the right direction for solving this issue?

Virtual folders and mailbox_list_get_root_forced
by Joan Moreau 02 Apr '21

02 Apr '21

Hi The function mailbox_list_get_root_forced returns sometimes the first or the second value of the INDEX param for the same mailbox. How to make sure this returns only the correct one of the corresponding mailbox ? mail_location = maildir:/var/vmail/%d/%n:LAYOUT=fs:INDEX=/var/mailindex namespace { location = virtual:/nix/store/toto-virtual:INDEX=/var/vmail/%d/%n/virtual prefix = virtual/ separator = / subscriptions = no } Thank you
